iilii NVENTD FK WITN E5 5 E5 W 'UNITED STATES PATENT OFFIC THOMAS OBRIEN, OF NEW YORK, N. Y.

BICYCLE.

SPECIFICATION forming part of Letters Patent No. 413,414, dated October 22, 1889.

Application filed June 10, 1889. Serial No. 313N734. (No model.)

To all whom it may concern:

Be it known that I, THOMAS OBRIEN, a citizen of the-United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful.

lighter without lessening the capacity of the machine.

In the drawings, Figure 1 is a side view of the bicycle without the saddle and handlebars. Fig. 2 is a plan thereof below the dotted lines X X. Fig. 3 is a plan view of the folding mechanism'and the connecting-spine O C. Fig. 4 is a top view of the folding mechanism, showing the slot and pinyand Fig. 5 is a side View, in a larger scale, of the standard-tube and folding combination.

The wheels A B and their axles and bearings, the chain and chain-wheel, and pedals may be of any desired construction.

Instead of having the folding mechanism above the forks of the wheel B as in my patout, No. 399,774, of March 19,1889, I place the folding mechanism lower down upon the standard F, and'the forks D D are carried higher upon said standard, by which greater strength is given to the connecting-frame.

The spine or reaches 0 G and forks D D are preferably made of sheet-steel, and the spine 0 C may be of two pieces, as shown in Fig. 3, or may be in one piece and carried around the split sleeve E, (see Fig. 5,) and in either case the said spine is iorged or pinned, or both, to the said split sleeve, and the neck G and spine 0 are made so as to form one piece. The ring K is made secure to the standard F for the split sleeve E to rest upon, and the tapered and slotted piece H is also made secure to the said standard closely above the said split sleeve, and the slot in H is cut downwardly only sufficient to receive the stop-pin H which is inserted at right angles in the bolt H and this bolt extends downwardly and is clutched between the jaws of the split sleeve, and when it is required to fold the machine the nuts E E of the bolt E are turned backwardly, and the bolt H is pulled up and turned to either side, when the machine may be folded.

The mud-guard N, carrying the steering standard 0, having been previously allowed to me and claim for the forks M being pend ing, these parts are shown in the drawings in combination with the parts herein claimed.

I claim as my invention- In a bicycle or other velocipede, the combination, with the wheels A B,,forks M M,

mud-guard N, and steering-standard O, of the spine 0 O and neck G, made in one piece,

standard F, ring K, split sleeveE, bolt E,-

and nuts, E E slotted piece H, bolt H, and stop-pin H forks D D, brace G, and split rin g G substantially as specified.

In testimony that Iclaim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 22d day of April, 1889.

THOMAS OBRIEN.
